RELATED APPLICATIONS

This application claims priority to U.S. provisional application No. 62/773,957, filed Nov. 30, 2018. The entire contents of the provisional application are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to frame rail assemblies for boat dock structures, and to an interlocking frame rail system for effectively and easily interlocking corresponding frame rails.

BACKGROUND OF THE INVENTION

Many boat dock structures are designed such that they may accommodate rub-rails. Rub-rails are often fastened to the sides of boat dock structures using mechanical fasteners, such as screws, nails, or bolts. This creates potential tear or fracture points along the rub-rails. Impact from watercraft vehicles may easily dislodge rub-rails that are mechanically fastened to the sides of boat docks. Thus, there is an ongoing need for rub-rails that may be securely coupled to the sides of boat dock structures.

Frame rails for boat docks exist in a variety of designs. A frame rail system may be designed to accommodate an existing boat dock structure; or conversely, a boat dock structure may be designed to accommodate an existing frame rail system. However, existing designs for frame rails fail to provide an effective and relatively simple means for interlocking corresponding frame rails so as to provide for the coupling of separate boat dock structures. In addition, the existing designs for frame rail systems fail to provide a means for effectively accommodating rub-rails, as described above.

Thus, there is an ongoing need for frame rail systems that provide an effective means for interlocking corresponding frame rails. There is also an ongoing need for frame rails that provide for the effective accommodation of rub-rails.

SUMMARY OF THE INVENTION

To address the foregoing problems, in whole or in part, and/or other problems that may have been observed by persons skilled in the art, the present disclosure provides methods, apparatus, instruments, and/or devices, as described by way of example in implementations set forth below.

According to one implementation, a boat dock structure includes an upper deck, sides extending downward from the upper deck, at least one of the sides having a cutout portion, and a wheel bumper having a substantially round shape. The wheel bumper has a first portion and a second portion, the first portion being positioned under the upper deck, the second portion extending outward from the cutout portion of at least one of the sides to protect the boat dock and a boat from damage when the boat is docking at the boat dock adjacent to the wheel bumper.

According to another implementation, a boat dock structure includes an upper deck, sides extending downward from the upper deck, a wheel bumper extending outward from at least one of the sides to protect the boat dock and a boat from damage when the boat is docking at the boat dock adjacent to the wheel bumper, and attaching structure configured to attach the wheel bumper to the boat dock, at least a portion of the attaching structure disposed under the upper deck such that the at least one of the sides is between the portion of the attaching structure and the boat.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a cut-away view of a portion of an implementation of a frame rail assembly 100 according to the present invention, showing a frame rail member 101 secured to a side of a boat dock structure 104. The frame rail assembly 100 may generally include the frame rail member 101 and a removable resilient rub-rail member 128. The frame rail member 101 generally includes a first side 102 configured for securing the frame rail member 101 to the side of the boat dock structure 104, a second side 108 opposing the first side 102, a first channel 116 extending along a length of the frame rail member 101, and a second channel 120 extending along the length of the frame rail member 101.

As illustrated in FIG. 1, the rub-rail member 128 may project outward from the second side 108. The rub-rail member 128 generally extends along at least a portion of the length of the frame rail member 101. The rub-rail member 128 may include a first coupling member 132 extending through the first channel 116 in engagement therewith, and a second coupling member 136 extending through the second channel 120 in engagement therewith. The first coupling member 132 and the second coupling member 136 generally extend continuously along a length of the rub-rail member 128. As also illustrated in FIG. 1, the first channel 116 may include an inner section 140 and an outer section 144 that opens at an outer surface of the frame rail member 101, where the inner section 140 has a larger cross-sectional area than the outer section 144. As further illustrated in FIG. 1, in some implementations a top surface 112 of the frame rail member 101 may be sloped and the outer section 144 of the first channel 116 may open at the top surface 112. The second channel 120 may include an inner section 148 and an outer section 152 that opens at an outer surface of the frame rail member 101, where the inner section 148 has a larger cross-sectional area than the outer section 152. The shapes of the first coupling member 132 and the second coupling member 136 may be complementary to the respective shapes of the first channel 116 and the second channel 120, such that the rub-rail member 128 may be limited to longitudinal insertion and removal by, e.g., slidably inserting the rub-rail member 128 into the frame rail member 101 or slidably removing the rub-rail member 128 from the frame rail member 101. For instance, the coupling members 132, 136 may not be removed by pulling them out from the frame rail member 101 in a direction perpendicular to the length of the frame rail member 101. The rub-rail member 128 may include an outer bumper shell 156 projecting outward from the second side 108 of the frame rail member 101, and an inner rib 160 disposed inside the outer bumper shell 156. The inner rib 160 may be configured for supporting the outer bumper shell 156 upon heavy impact, and may be oriented so as to be less deformable than the outer bumper shell 156. For example, the inner rib 160 may project outward from the frame rail member 101 such that the inner rib 160 comes into contact with the outer bumper shell 156 upon heavy impact, thus creating a support mechanism for keeping the outer bumper shell 156 from coming into contact with the frame rail member 101 upon heavy impact from watercraft vehicles. The rub-rail member 128 may include at least one raised ridge 164 for improved traction. The removable rub-rail member 128 may be constructed from, for example, high-density polyurethane, polyethylene, or various other types of polymers.

The frame rail member 101 may be made of, for example, extruded aluminum with engineered first and second channels 116, 120. As illustrated in FIG. 1, the frame rail member 101 may include one or more toe members 168 for securing the first side 102 of the frame rail member 101 to the side of the boat dock structure 104. The frame rail member 101 may be configured such that a user may subsequently construct the boat dock structure 104 to accommodate the frame rail member 101; or the user may secure a frame rail to an existing side of a boat dock structure (as discussed below with respect to FIG. 5). Those of skill in the art will appreciate that the frame rail member 101 may be secured to the side of the boat dock structure 104 by any suitable means.

It will be understood that the term “boat dock structure” is not meant to limit the scope of the invention to use in conjunction with boat dock structures such as boat docks, fingers and headwalks. The term “boat dock structure” as used herein may encompass any and all types of structures that may utilize the present invention, such as, for example, automobile trailers, buildings and the like.

FIG. 2 is a cut-away view of a portion of another implementation of a frame rail assembly 200 according to the present invention, showing a frame rail member 201 secured to a side of the boat dock structure 104. FIG. 2 illustrates a rounded top surface 212 of the frame rail member 201 and an alternative location for a first channel 216 of the frame rail member 201, and accordingly illustrates an outer section 244 and an inner section 240 of the first channel 216. In the present example, the outer section 240 of the first channel 216 opens at the rounded top surface 212 of the frame rail member 201. In the present implementation illustrated in FIG. 2, a first coupling member 232 of a removable rub-rail member 228 is complementary in shape to the first channel 216 of the frame rail member 201, thus limiting the rub-rail member 228 to longitudinal insertion into and removal from the frame rail member 201. The frame rail assembly 200 may be utilized as described above with respect to FIG. 1, or as otherwise described herein.

FIG. 3 is a cut-away view of a portion of another implementation of a frame rail assembly 300 according to the present invention, showing a frame rail member 301 secured to a side of the boat dock structure 104. FIG. 3 illustrates a substantially flat top surface 312 of the frame rail member 301 and an alternative location for a first channel 316 of the frame rail member 301, and accordingly illustrates an outer section 344 and an inner section 340 of the first channel 316. In the present example, the outer section 340 of the first channel 316 opens at the substantially flat top surface 312 of the frame rail member 301. The first channel 316 extends from the top surface 312 of the frame rail member 301 in a direction perpendicular to the length of the frame rail member 301. A first coupling member 332 of a removable rub-rail member 328 is complementary in shape to the first channel 316 of the frame rail member 301, thus limiting the rub-rail member 328 to longitudinal insertion into and removal from the frame rail member 301. The frame rail assembly 300 may be utilized as described above with respect to FIG. 1 and FIG. 2, or as otherwise described herein.

FIG. 4 is a cut-away view of a portion of another implementation of a frame rail assembly 400 according to the present invention, showing a frame rail member 401 secured to a side of the boat dock structure 104.

FIG. 4 illustrates an alternative location for a first channel 416 of the frame rail member 401, and accordingly illustrates an outer section 444 and an inner section 440 of the first channel 416. The outer section 444 of the first channel 416 opens to the first side 102 of the frame rail member 401. A first coupling member 432 of the removable rub-rail member 428 is complementary in shape to the first channel 416 of the frame rail member 401, thus limiting the rub-rail member 428 to longitudinal insertion into and removal from the frame rail member 401. The frame rail assembly 400 may be utilized as described above with respect to FIGS. 1 through 3, or as otherwise described herein.

FIG. 5 is a cut-away view of a portion of another implementation of a frame rail assembly 500 according to the present invention, showing a frame rail member 501 secured to a side of a boat dock structure 504. FIG. 5 illustrates an alternative shape for a second channel 520 of the frame rail member 501, and accordingly illustrates an outer section 552 and an inner section 548 of the second channel 520. A second coupling member 536 of a removable rub-rail member 528 may be complementary in shape to the second channel 520 of the frame rail member 501, thus limiting the rub-rail member 528 to longitudinal insertion into and removal from the frame rail member 501. As also illustrated in FIG. 5, a user may secure the frame rail member 501 (or any of the other frame rail members 101, 201, 301, 401) to the side of an existing boat dock structure 504 through the use of mechanical fasteners, such as counter-set screws 568, nails, or the like, or, for example, through welding. Alternatively, the frame rail member 501 may be configured such that a user may subsequently construct a boat dock structure to accommodate the frame rail member 501, as previously noted. All such methods entailing the use of the frame rail member 501 are encompassed by the present invention.

FIG. 6 is a cut-away view of a portion of another implementation of a frame rail assembly 600 according to the present invention, showing a first rub-rail member 628 and a second rub-rail member 629. As illustrated in FIG. 6, the frame rail assembly 600 may generally include a frame rail member 601, the first removable resilient rub-rail member 628, and the second removable resilient rub-rail member 629. The frame rail member 601 may include a first side 602 configured for securing the frame rail member 601 to a side of a boat dock structure, a second side 608 opposing the first side 602, an upper section 623 between the first side 602 and the second side 608, a first channel 616 extending along a length of the frame rail member 601, a second channel 620 extending along the length of the frame rail member 601, and a lower section 624 between the first side 602 and the second side 608. The first channel 616 may generally be located in the upper section 623 of the frame rail member 601. The second channel 620 may generally be located below the first channel 616. The first rub-rail member 628 generally projects outward from the second side 608 and extends along at least a portion of the length of the frame rail member 601. The first rub-rail member 628 may include a first coupling member 632 extending through the first channel 616 in engagement therewith, and a second coupling member 636 extending through the second channel 620 in engagement therewith. The first channel 616 may include an inner section 640 and an outer section 644, where the inner section 640 has a larger cross-sectional area than the outer section 644. The second channel 620 may include an inner section 648 and an outer section 652, where the inner section 648 has a larger cross-sectional area than the outer section 652. The shapes of the first coupling member 632 and the second coupling member 636 may be complementary to the respective shapes of the first channel 616 and the second channel 620, such that the first rub-rail member 628 may be limited to longitudinal insertion and removal. The first rub-rail member 628 may include an outer bumper shell 656 projecting outward from the second side 608 of the frame rail member 601, and an inner rib 660 disposed inside the outer bumper shell 656. The inner rib 660 may generally be configured for supporting the outer bumper shell 656 upon heavy impact, and may be oriented so as to be less deformable than the outer bumper shell 656.

As further illustrated in FIG. 6, the frame rail member 601 may generally include a third channel 617 in the lower section 624 of the frame rail member 601 extending along the length of the frame rail member 601, a fourth channel 621 generally located above the third channel 617 and extending along the length of the frame rail member 601, and the second removable resilient rub-rail member 629 projecting outward from the second side 608 of the frame rail member 601 and extending along at least a portion of the length of the frame rail member 601. The second rub-rail member 629 may include a third coupling member 633 extending through the third channel 617 in engagement therewith, and a fourth coupling member 637 extending through the fourth channel 621 in engagement therewith. The third channel 617 may include an inner section 641 and an outer section 645, where the inner section 641 has a larger cross-sectional area that the outer section 645. The fourth channel 621 may include an inner section 649 and an outer section 653, where the inner section 649 has a larger cross-sectional area than the outer section 653. The shapes of the third coupling member 633 and the fourth coupling member 637 may be complementary to the respective shapes of the third channel 617 and the fourth channel 621, such that the second rub-rail member 629 may be limited to longitudinal insertion and removal. The second rub-rail member 629 may include an outer bumper shell 657 projecting outward from the second side 608 of the frame rail member 601, and an inner rib 661 disposed inside the outer bumper shell 657. The inner rib 661 may generally be configured for supporting the outer bumper shell 657 upon heavy impact, and may be oriented so as to be less deformable than the outer bumper shell 657.

As further illustrated in FIG. 6, the first rub rail member 628 may include a section 612 that is adjacent to the first side 602 of the frame rail member 601 and which may be interposed between the first side 602 of the frame rail member 601 and the side of the boat dock structure (not shown). The second rub-rail member 629 may include a section 613 that is adjacent to the first side 602 of the frame rail member 601 and which may be interposed between the first side 602 of the frame rail member 601 and the side of the boat dock structure (not shown).

Those skilled in the art will recognize that the frame rail member 601 may be configured to accommodate one rub-rail member, or a plurality of rub-rail members. For example, in one implementation, the second rub-rail member 629 may be removed from the frame rail assembly 600. The first rub-rail member 628 may be configured such that the outer bumper shell extends below the fourth channel 621, so as to cover, or partially cover the fourth channel 621, as illustrated by a phantom line 670. Those skilled in the art will also recognize that the frame rail members described herein may be utilized in conjunction with the interlocking frame rail system described below. As but one example, and as will become evident from the discussion below, the first rub-rail member 628 and the second rub-rail member 629 may be removed from the frame rail member 601, and the frame rail member 601 may be interlocked with a corresponding frame rail member.

The first channel 718 may include an inner section 740 and an outer section 744, the inner section 740 having a larger cross-sectional area than the outer section 744.

In the present example, the second frame rail member 705 may generally include a first side 707 configured for securing the second frame rail member 705 to a side of a second boat dock structure (not shown), a second side 711 opposing the first side 707, an upper section 715 between the first side 707 and the second side 711, a first channel (or upper channel) 719 in the upper section 715 and extending along a length of the second frame rail member 705, a second channel (or first intermediate channel) 723 extending along the length of the second frame rail member 705, and a lower section 727 between the first side 707 and the second side 711. The second channel 723 may generally be located below the first channel 719. The first channel 719 may include an inner section 741 and an outer section 745, the inner section 741 having a larger cross-sectional area than the outer section 745.

As illustrated in FIG. 7, the first frame rail member 704 may include a third channel (or lower channel) 750 extending along the length of the first frame rail member 704 in the lower section 726 of the first frame rail member 704, and a fourth channel (or second intermediate channel) 754 above the third channel 750, the fourth channel 754 extending along the length of the first frame rail member 704.

FIG. 8 is a perspective view of a portion of the first frame rail member 704 illustrated in FIG. 7. As illustrated in FIG. 7 and FIG. 8, in some implementations, the first frame rail member 704 may include at least one toe member 730 for securing the first side 706 of the first frame rail member 704 to the side of the first boat dock structure 702 (as shown in FIG. 7).

FIG. 9 is a perspective view of a portion of the connector member 900 that may be utilized in the interlocking frame rail system 700 according to the present invention. The connector member 900 illustrated in FIG. 9 may be used to interlock the first frame rail member 704 and the second frame rail member 705 shown in FIG. 7. The connector member 900 may include a first coupling member 902 and a second coupling member 904. The first coupling member 902 and the second coupling member 904 may extend continuously along the length of the connector member 900. An interlocking frame rail system 700 according to the present invention may include an upper connector member and a lower connector member, one or both of which may be configured as the illustrated connector member 900. Alternatively, the interlocking frame rail system 700 may include only an upper connector member, or only a lower connector member. When the connector member 900 is utilized as an upper connector member, the connector member 900 may extend along at least a portion of the length of the first frame rail member 704 and at least a portion of the length of the second frame rail member 705. The first coupling member 902 may extend through the first channel 718 of the first frame rail member 704 in removable engagement therewith, and the second coupling member 904 may extend through the first channel 719 of the second frame rail member 705 in removable engagement therewith. The first coupling member 902 may be complementary in shape to the first channel 718 of the first frame rail member 704, and the second coupling member 904 may be complementary in shape to the first channel 719 of the second frame rail member 705, thus limiting the connector member to longitudinal insertion into and removal from the first and second frame rail members 704, 705.

Continuing with the present example, when the connector member 900 is utilized as a lower connector member, the connector member 900 may extend along at least a portion of the length of the first frame rail member 704 and at least a portion of the length of the second frame rail member 705. The first coupling member 902 may extend through the third channel 750 of the first frame rail member 704 in removable engagement therewith, and the second coupling member 904 may extend through the third channel 751 of the second frame rail member 705 in removable engagement therewith. The first coupling member 902 may be complementary in shape to the third channel 750 of the first frame rail member 704, and the second coupling member 904 may be complementary in shape to the third channel 751 of the second frame rail member 705, thus limiting the connector member 900 to longitudinal insertion into and removal from the first and second frame rail members 704, 705.

Those of skill in the art will appreciate that the connector member 900 may be constructed of various materials, such as extruded aluminum or various types of polymeric materials, including resilient materials. The connector member 900 may also include a projection 906 that may act as a spacer between the first frame rail member 704 and the second frame rail member 705.

FIG. 10 is an elevation view of the interlocking frame rail system 700 illustrated in FIG. 7 and the connector member 900 illustrated in FIG. 9, showing the first coupling member 902 of the connector member 900 extending through the first channel 718 of the first frame rail member 704 in removable engagement therewith, and the second coupling member 904 of the connector member 900 extending through the first channel 719 of the second frame rail member 705 in removable engagement therewith. As illustrated in FIG. 10, the first coupling member 902 is shaped complementarily to the first channel 718 of the first frame rail member 704, and the second coupling member 904 is shaped complementarily to the first channel 719 of the second frame rail member 705, thus limiting the connector member 900 to longitudinal insertion into and removal from the first and second frame rail members 704, 705. The projection 906 of the connector member 900 acts as a spacer between the first frame rail member 704 and the second frame rail member 705, and extends into a gap 780 between the second side 710 of the first frame rail member 704 and the second side 711 of the second frame rail member 705.

FIG. 36 is a view of a portion of another implementation of a frame rail assembly 3600 according to embodiments of the present invention. The frame rail assembly 3600 may generally include a frame rail member 3601, a first removable rub-rail member 3602, and a second removable rub-rail member 3604. The frame rail assembly 3600 is similar to the frame rail assembly 600 of FIG. 6 in that the frame rail member 3601 includes channels 3603 for connecting to the connecting members of the first and second rub-rail members 3602, 3604.

The first removable rub-rail member 3602 may include an outer bumper shell 3606 projecting outward from the side of the rub-rail member 3602 with inner ribs. The frame rail member 3601 may be configured to accommodate one rub-rail member, or a plurality of rub-rail members. For example, in one implementation, the second rub-rail member 3604 may be removed from the frame rail assembly 3601. The first rub-rail member 3602 may be configured such that the outer bumper shell 3606 has an extended portion 3608 that may extend below the channel 3603, so as to cover, or partially cover the channel 3603 when the second rub-rail member 3604 is not used.

The second rub-rail member 3604 may be configured to have a flat outer surface, without an outer bumper shell, in contrast to the embodiment of FIG. 6. This allows the frame rail assembly 3601 and any associated parts to be hidden from view. Additionally, the second rub-rail member 3604 may have an extended portion 3610 extending downwards from the boat dock frame to provide added protection thereto.
